7 Attachment 2 NOC-AE Page 1 of 4 SOUTH TEXAS PROJECT UNITS 1 AND 2 PROPOSED TECHNICAL SPECIFICATION CHANGE TO REMOVE THE POST-ACCIDENT SAMPLING SYSTEM FROM SERVICE 1.0 INTRODUCTION 1.1 Proposed Change DESCRIPTION AND ASSESSMENT This proposed License Amendment Request is a request pursuant to 10CFR50.90 to revise Technical Specification a, "Primary Coolant Sources Outside Containment," and d, "Post-Accident Sampling," consistent with removing the Post-Accident Sampling System (PASS) from service. 1.2 Proposed Technical Specification Changes See Attachment Revised Technical Specifications See Attachment Updated Final Safety Analysis Report 2.0 BACKGROUND Implementation of the change proposed by this amendment request will require revision of the South Texas Project Updated Final Safety Analysis Report and the Emergency Plan. Westinghouse Owners Group (WOG) topical report WCAP A Rev. 2, "Post Accident Sampling System Requirements: A Technical Basis," evaluated the PASS requirements to determine their contribution to plant safety and accident recovery. The topical report considered the progression and consequences of core damage accidents and assessed the accident progression with respect to plant abnormal and emergency operating procedures, severe accident management guidance, and emergency plans. WCAP A, Rev. 2, concluded that the current PASS samples specified in NUREG 0737, "Clarification of TMI Action Plan Requirements," may be eliminated. 3.0 DESCRIPTION OF THE PROPOSED CHANGE South Texas Project Technical Specification a, "Primary Coolant Sources Outside Containment," states that a program shall be established, implemented, and maintained:... to reduce leakage from those portions of systems outside containment that could contain highly radioactive fluids during a serious transient or accident to as low as practical levels. The systems include the containment spray, Safety Injection, containment hydrogen monitoring, post-accident sampling and primary sampling. The program shall include the following: 1) Preventive maintenance and periodic visual inspection requirements, and 2) Integrated leak test requirements for each system at refueling cycle intervals or less.

8 Attachment 2 NOC-AE Page 2 of 4 South Texas Project Technical Specification d, "Post-Accident Sampling," states that a program shall be established, implemented, and maintained:... which will ensure the capability to obtain and analyze reactor coolant, radioactive iodines and particulates in plant gaseous effluents, and containment atmosphere samples under accident conditions. The program shall include the following: 1) Training of personnel, 2) Procedures for sampling and analysis, and 3) Provisions for maintenance of sampling and analysis equipment. The reference to post-accident sampling is to be removed from a, and d is to be deleted altogether. The changes are consistent with NRC-approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler TSTF-366 (Reference 1). Availability of this technical specification improvement was announced in Federal Register Volume 65, No. 211 (Reference 2), on October 31, 2000, as part of the Consolidated Line Item Improvement Process (CLIIP). 4.0 TECHNICAL ANALYSIS 4.1 Applicability of Published Safety Evaluation The South Texas Project has reviewed the safety evaluation published as part of the CLIIP. This verification included a review of the NRC staff's evaluation as well as the supporting information provided to support TSTF-366 (i.e., WCAP A, Rev. 2, "Post Accident Sampling System Requirements: A Technical Basis," submitted October 26, 1998, as supplemented by letters dated April 28, 1999, April 10, 2000, and May 22, 2000). The review included the NRC safety evaluation of WCAP The South Texas Project has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to the South Texas Project, and justify this amendment incorporating the proposed changes to the South Texas Project Technical Specifications. 4.2 Optional Changes and Variations The South Texas Project is not proposing any variations or deviations from the technical specification changes described in TSTF-366 or in the NRC staff's model safety evaluation published in the Federal Register October 31, The South Texas Project Technical Specifications include an administrative requirement for a program for those portions of systems outside containment which contain highly radioactive fluids to minimize leakage during a serious transient or accident. PASS is specifically listed in Technical Specification a as falling under the scope of this requirement. As described in the staff's model safety evaluation published on October 31, 2000, the South Texas Project proposes to implement the appropriate controls such that PASS will not be a potential leakage path for highly radioactive fluids outside containment. These controls will be applied during the implementation period for this amendment

9 Attachment 2 NOC-AE Page 3 of 4 such that it is appropriate to delete reference to PASS from Technical Specification a. 5.0 REGULATORY ANALYSIS 5.1 No Significant Hazards Determination The South Texas Project has reviewed the safety evaluation published as part of the CLIIP. The South Texas Project has concluded that the proposed determination presented in the notice is applicable to the South Texas Project and there are no significant hazards associated with this change. The determination is hereby incorporated by reference to satisfy the requirements of 1 OCFR50.91 (a). 5.2 Verification and Commitments Pursuant to the notice of availability published in the Federal Register (Reference 2) for this technical specification amendment request, the South Texas Project has addressed the following plant-specific verifications and commitments: 1. The South Texas Project will develop contingency plans for obtaining and analyzing highly radioactive samples of reactor coolant, containment sump, and containment atmosphere. The contingency plans will be maintained in the plant procedures. Maintaining the contingency plans is considered a regulatory commitment. Implementation is expected within six months following NRC approval of the proposed change. 2. The South Texas Project has developed a capability for classifying fuel damage events at the Alert level threshold for 2-5% core damage. This level of core damage is associated with radioactivity levels of 300 jici/ml dose equivalent iodine. This capability for the Alert classification will be maintained in emergency plan implementing procedures. Maintaining the capability of classifying fuel damage events is considered a regulatory commitment. Implementation is expected within six months following NRC approval of the proposed change. 3. The South Texas Project has established the capability to monitor radioactive iodines that have been released to offsite environs. This capability is maintained in the emergency plan implementing procedures. Maintaining the capability to monitor such radioactive iodines is considered a regulatory commitment. 5.3 Implementation The South Texas Project requests NRC approval of this proposed Technical Specification change by January 31, Implementation is expected within six months following NRC approval of the proposed change. 6.0 ENVIRONMENTAL EVALUATION The South Texas Project has reviewed the environmental evaluation included in the model safety evaluation published on October 31, 2000, as part of the CLIIP. The South
